At a 3:15 p.m. news conference, police declined to identify a 17-year-old boy who was also shot at the scene and who remains in criticial condition in a local hospital. Holmes and the 17-year-old knew each other, Connellan said.

Neither Holmes nor the 17-year-old were members of a gang and neither had an extensive criminal record, Connellan said.

Investigators do not know the motive for the attack, he said. No arrests have been made.

He said one or both of the victims was on a bicycle when the shots were fired. He would not provide any details about the number of times each victim was shot or where they were struck.

"We do not have a lot of suspect information," Connellan said.

Police request that any witnesses to the shooting call investigators at 315-442-5222.
